This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
The read-only property RTCDataChannel.readyState returns an enum of the type RTCDataChannelState representing the state of the underlying data connection.
Syntax
var state = dataChannel.readyState;
The possible values are:
"connecting"is the state indicating that the underlying connection is not yet set up and active. This is the initial state of a data channel created withRTCPeerConnection.createDataChannel()."open"is the state indicating that the underlying connection is up and running. This is the initial state of a data channel dispatched in aRTCDataChannelEvent."closing"is the state indicating that the underlying connection is in the process of shutting down. No new sending task is accepting but the cached messages are in the process of being sent, or received."closed"is the state indicating that the underlying connection has been shut down (or couldn't be established).
Example
var pc = new RTCPeerConnection();
var dc = pc.createDataChannel("my channel");
console.log("Channel state: " + dc.readyState);
